Respuesta :
you have a 1/6 chance for a red and a 2/6 or a 1/3 chance of a green bead. you have to count the yellow (and all color)beads in the denominator ;) . I hope this answer helps
3 yellow, 1 red, 2 green....total of 6 beads
P(drew a red bead) = 1/6
without replacing
P(drew a green bead) = 2/5
P(both events) : 1/6 * 2/5 = 2/30 reduces to 1/15 <=
